Lake Toya is praised as one of the “Top 100 Views of Japan.” It is located within Shikotsu-Toya National Park. This perfect circular ice-free lake is a natural masterpiece. It was formed by a volcanic eruption tens of thousands of years ago. The lake water is crystal clear.
The lake is surrounded by Showa Shinzan, which constantly emits white smoke. You can also see the active volcano Mt. Usu. Mt. Yotei, known as the “Mt. Fuji of Hokkaido,” stands in the distance. Every season offers postcard-like views. This guide introduces the best activities for both summer and winter.
Lake Toya Attraction Guide: Sightseeing Cruises, Mt. Usu, and Volcano Landscapes
🚢 Summer Limited: Nakajima Island Landing Adventure (Late April – End of October)
In the warm season, the sightseeing cruise is not just a cruise on the lake, but will also take you to land on “Nakajima Island” in the center of the lake. This is a healing journey of about 50 to 80 minutes. It is highly recommended to get off the boat and walk around:
Nakajima Shrine: Pray for peace and good luck deep in the heart of the lake.
Forest Bathing Trail: Stroll through the natural forest filled with negative ions; with good luck, you might even encounter wild Ezo sika deer.
Lake and Forest Museum: Delve deep into the ecological evolution of this active volcanic lake.






🎆 Pinnacle of Romance: Lake Toya Long-Run Fireworks Festival (Every Night in Summer)
From late April to late October every year, Lake Toya stages Japan’s longest-running “Fireworks Festival.” The fireworks are launched punctually at 20:45 every night, with 20 minutes of brilliant fireworks blooming over the lake surface.
Local Insider Way to Play: Take a specially chartered “Fireworks Viewing Boat” to watch the brilliant fireworks from the center of the lake at eye level. The sense of shock is completely different from watching from the shore, making it a must-include item on the checklist for couples’ dates or family travel!
❄️ Winter Limited: Peaceful Cruise in a Silver White World (November – Early April)
Although landing on the island is not possible in winter due to safety considerations, what you get in return is a picturesque snow scene. Take a round-the-lake route of about 30–45 minutes to watch the azure lake water interweave with the silver snow on the shore. The world becomes so quiet that only the sound of ice-breaking remains; this pure beauty can only be understood through personal experience.
